[ Introduction ]

Today we have Gainward’s new special edition GTX 780 graphics card known as the Phantom GLH “Goes Like Hell”. With a name like that you would expect the GTX 780 Phantom GLH to be pretty fast and Gainward assures us it is. They say it provides GTX Titan like performance and we plan to find out if their claim is accurate... Nvidia set a new benchmark for GPU performance back in March of 2013 with what can only be described as the epic GeForce GTX Titan. Armed with a mind blowing 2688 stream processors, it took 7.1 billion transistors to put the Titan together. The 256-bit wide memory bus of the GeForce GTX 680 was also dumped for a more efficient 384-bit bus which boosted the peak memory bandwidth to 288.4GB/s, 50% more than the GTX 680. In the end we described the GTX Titan as being in a master class of what is technically possible and although that made it a fairly niche product, it's a niche product that had no trouble manhandling the other top single-GPU cards by Nvidia and AMD. A few months later and Nvidia was ready to release a slightly cut down version of the $1000 GTX Titan. Now known as the GTX 780 this new GPU still features 7.1 billion transistors and a 384-bit wide bus for a memory bandwidth of 288.4GB/s. The changes were instead made to the GPU configuration, which saw the GTX 780 downgraded to 2304 SPU’s with 192 TAU’s while the ROPs remained at 48. The mere 14% reduction in SPUs and TAUs meant that on average the GTX 780 was just 14% slower than the GTX Titan while costing around 35% less. Traditionally AMD and Nvidia’s board partners are able to boost performance of most GPU’s by around 5-10% through factory overclocking, so 14% didn’t seem like a serious stretch. Gainward has answered the bell with their GTX 780 Phantom GLH. Whereas the GeForce GTX 780 is traditionally clocked at 863MHz with an average boost clock of 902MHz, Gainward has increased these frequencies to 980MHz and 1033MHz. This is a 14% increase for the base core clock speed and Gainward say it is enough to dethrone the GTX Titan. Previously we have only seen water-cooled GTX 780 cards pushed this far, while most air-cooled solutions maxed out at around 960MHz, at least as far as factory overclocking has been concerned. However the GTX 780 Phantom "GLH" is no ordinary graphics card, featuring a massive heatsink and three large fans it is able to keep the GTX 780 core cool even when under heavy load.

ProX	Posted on: 07/12/2013 11:06 AM HUGE graphics card!!! With just two of these installed you must have had no room left in your PC Nice review though.
